GENERAL INFORMATION—CONTINUED

NOTE:  INDOOR INSTALLATIONS: DO NOT suspend the evaporative cooling module—it must be 

mounted on a platform. If the installation location does not have a suitable platform that allows 

the module to be installed directly to the cabinet, install the module on a separate platform with a 

compatible field-fabricated transition duct between the module and the cabinet.

 

Ensure that all components listed in 

Table 1

 are available before beginning installation. These components are 

shipped with the evaporative cooling module.
